Explain this please ..The other day I uploaded an image of my dogs
400 x 165
and it took and was showing but thought it still too big so after resizing it still smaller ,today, I tried to upload a 250 x 99 version image and it was too large with the setting being at 2kb
Are you trying to upload the image to the FTF server? Try hosting it elsewhere like Photobucket or Imageshack, and then use [img] tags. This will also help save bandwidth for the FTF servers since it won't have to transfer the image everytime someone views your sig.
